Stripes
Medical Surgery
Ireland
Cows
Elvis
Music
Newspapers/yearbook
I love the pbteen bedspread-http://www.pbteen.com/products/p3249/ind...
But I have no clue how to garnish the rest of my room,(ie, painting the walls) so if u have any tips, please permit me know. Thanks ya'll!
P.S.-How the heck do you keep your room clean?
Decorators: Need sustain select wall color -?
Answers:    Paint your room like blue green color as in the bedspread.Then paint the border of your room brown.Maybe product 2 stripes instead of only 1.Maybe on the walls you could paint soccer balls adjectives around.Put up green curtains to make your room very colorful.
For decorate your room put a big nice framed picture of Ireland above your bed.Build small shelves in your room and all your favorite things on it.Because you approaching cows you could keep a cow pillow on your bed.Also because you like music buy a CD rack from Target or Walmart.That style you can store all of your music.If you have hardwood floors put a cool rug on the ground.
P.S.-The with the sole purpose way my room stays clean is because if I hand down anything on the floor,my dog will chew it.
